To all whom it may concern Be it known that we, BOUDEWIJN B. XEL'TEBOOM,a sub ect of the Queen of the Netherlands, and CECIL HAMELIN TAYLOR,

a citizen of the United States, residing at Detroit, county of \Vayne,State of Michigan, have invented certain new and useful Improvements inExplosion-Engines, and declare thefollowing to be a full, clear, and,exact description of the same, such as will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

Our invention relates to explosion enginesand an object of ourimprovements is to provide an improved construction in which the variouspassages may be properly formed in the casting and in which saidpassages may be effectively cooled, cleaned and inspected. WVe securethis object in the device illustrated in the accompanying drawings inwhich,

Figure 1, is a side elevation of an enbloc casting of a four-cylinderengine, the cover plate being removed. Fig. 2, is an elevation of saidcover plate separate from the casting. Fig. 3, is a section on the lineC-C Figs. 1 and 2. Fig. 4, is a section on the line DD Figs. 1 and 2..Fig. 5, is a plan view, the head of the cylinder being removed and theplate shown secured in place at the side of the cylinder casting. Fig.6, is an elevation showing the inside of the cover plate. Fig. 7, is asection on the line GG Figs. 1," 2 and 5.

a a is the pa.rt of the casting including the cylinders.

12 indicates the removable cover plate.

The casting a is provided with a water jacket opening at the side nearthe top and into the casting and through the water jacket extend theintake passages (Z1! and exhaust passages e c e 0. These passages extendto the various valves 7' and 7:: and are surrounded by the water spaceg, 9 also opening at the side of the casting toward the top thereof.

0 is a portion of an intake manifold formed in the casting a.

The water space 5 the portion of the manifold c and the openings fromthe passages e e e e are surrounded by walls which are faced off attheir outer edges.

The cover plate 6 is provided with an exhaust manifold f extendinglongitudinally thereof along its upper portion and is provided with thecomplementary portion 0 of the intake manifold and also with openings 2?i 2' 2'. corresponding to and adapted to register with, the openings 6 ce a and opening into the exhaust manifold f. The cover plate I) is coredout for a water space and is provided with openings m m communicatingwith said water space and with the water space g in the casting a whenthe cover plate is in place.

n n n are bolt holes in the casting a and 0 0 0 are corresponding holesin the cover plate I). The cover plate is placed against the sides ofthe cylinder a, the faced-off surfaces shown in Fig. (3 fitting againstthe faced-off surfaces above described upon the casting a, a properjoint is formed between the casting a and the cover plate 7), and thecover plate is held in place by bolts passing into the apertures m 0.

is the opening in which the cooling water passes into the water space ofthe cover I) and thence through holes on m in the water space of thecasting a.

j, j, j, j are exhaust valves. [ski-:10 are intake valves, these valvesare in line with each other and their stems in one plane parallel to theplane of the axis of the cylinders in the casting a.

By this arrangement we secure a casting in which the various passagesare formed with the water space surrounding them and the casting can bereadily observed as to the perfection of the walls of these passages,the intake passages may be completely clean including the intakemanifold, and the parts may be readily assembled and the various coreseasily and properly supported.

What we claim is:

1. A cylinder casting having an intake manifold, said casting consistingof two parts, the dividing plane between said parts passinglongitudinally through said manifold so as to cut a main passage of saidmanifold longitudinally dividing it into two parts that are accessiblefor cleaning the interior walls when the parts are parted.

2. A cylinder casting having a water space, an intake manifold and gaspassages, said casting consisting of two parts, the dividing planebetween said two parts passing longitudinally through said intakemanifold and cutting said passages and space.

3. A cylinder casting having a water space, an intake manifold and gaspassages,

said casting consisting of two parts, the-dividing plane between saidtwo parts passing longitudinally through said intake manifold andcutting said passages and space, said passages being surrounded by saidwater space so that the interior of their walls shall be accessible forcleaning when the parts are separated.

4. A cylinder casting consisting in part of a removable plate, saidcasting having an intake manifold, an exhaust manifold, and water spaceso that the interior of their walls shall be accessible for cleaningwhen the parts are separated, a part of the intake manifold being insaid removable plate,.

valve passages and the complementary part of the intake manifold in theother of said parts, said plate being adapted to be secured to the otherof said parts so as to complete said intake manifold and secure aconnection between the water spaces in the two parts, and acommunication between the exhaust manifold and the exhaust passages ofthe other of said parts. v

5. A cylindercasting consisting in part of a removable plate, saidcasting having an intake manifold, an exhaust manifold and Water space,a part of the intake manifold being in said removable plate, valvepassages and the complementary part of the intake manifold in the otherof said parts,

said. plate being adapted to be secured to the other of said parts so asto complete said intake manifold and secure a connection between thewater spaces and the two parts, and a communication between theexhaustmanifold and the exhaust passages of the other of said parts,wallsof said passages and manifolds being in said water space.

6. A casting embodying a plurality of cylinders provided with gaspassages and water space, said casting consisting of two parts divisiblein a plane parallel to a plane through the axes of the several cylindersand cutting said passages and water space.

7. The combination with a plurality of cylinders, a plurality of valvestherefor having their stems in one plane, passages leading to and fromthe ports of said valves, said cylinders being divided in a planesubstantially parallel to the plane through the valve stems of saidvalves, said plane cutting said passages and adjacent water space so asto render the walls of the passage accessible for cleaning.

In testimony whereof, we sign this specification in the presence of twowitnesses.
